Odom was very large with its body covered in black fur. It had three fingers on each hand, its head resembled something like a moth with a pair of antenna in its bumpy forehead, its eyes appear to feature eyeshine and its mouth contained a pair of tiny mandibles.

At some unknown point in time Odom was captured by Dr. Rainuma and his scientists. He kept it in a large sealed cage for a while, until he had figured the perfect weapon against demons in the acid caused by the DevilmanMico's demon suit Tollg. He used the acid and made Biological Bullets and then sent a pair of Demon Busters to test the new weapon on Odom, it instantly leaps at them but is shot with the bullets were it simply stands and stares a few seconds before melting into a steaming pile of sludge.
